Custom software for recruitment

We build bespoke systems for recruitment organisations: candidate and placement tracking, compliance document collection and client portals. Each one is shaped around how your team works and connected to the software you already rely on.

Systems we build

Typical recruitment projects. Each is scoped to your process, not a template.

  • AI-Powered Candidate Matching Engine

    A machine learning system that analyses job requirements and candidate profiles using natural language processing, semantic matching, and skills taxonomy mapping to surface the best-fit candidates from the agency's database and external sources.

  • Contractor and IR35 Management Platform

    A comprehensive platform for managing contractor engagements including Status Determination Statement creation and distribution, contract management, timesheet approval, invoice processing, and IR35 audit trail maintenance. Integrates with HMRC CEST tool outputs.

  • Multi-Channel Job Board Integration Hub

    A centralised job distribution platform that publishes vacancies to Reed, Indeed, Totaljobs, LinkedIn, and sector-specific job boards from a single interface, tracks applications from each source, and provides cost-per-hire analytics by channel.

  • Temporary Staffing Workforce Management System

    A platform for temp agencies that manages worker availability, shift allocation, client booking requests, timesheet capture, AWR qualifying period tracking, and automated payroll and billing generation with margin reporting.

  • Recruitment CRM with Business Development Tools

    A CRM system designed for recruitment consultants that tracks client relationships, job pipeline, placement revenue forecasts, and consultant activity KPIs. Includes automated client engagement sequences and market intelligence dashboards.

Problems we hear about

The issues that usually prompt the first conversation.
  • Recruiters spend much of their time on administrative tasks including CV screening, interview scheduling, and compliance paperwork rather than building client and candidate relationships
  • IR35 off-payroll working rules (Chapter 10 ITEPA 2003) require medium and large end clients to make Status Determination Statements for every contractor engagement, creating compliance complexity for agencies
  • The Employment Agencies Act 1973 and Conduct Regulations 2003 impose specific requirements for opt-outs, terms of business, advertising, and record-keeping that manual processes frequently fail to meet
  • Candidate data management at scale creates significant UK GDPR exposure, with recruitment databases often containing outdated records, no lawful basis documentation, and inadequate consent management
  • Multi-channel candidate sourcing across job boards, LinkedIn, referrals, and career pages generates duplicate records and inconsistent data that makes reporting and pipeline management unreliable

Off-the-shelf or custom?

There are good off-the-shelf products for most of recruitment. If one fits your process, use it; we will tell you if we think so. Custom software makes sense when your process is distinctive, when you are joining several tools together by hand, or when a product forces your team into workarounds every day.

Rules we design around

Legislation and standards that commonly shape systems in this sector. We design with them in mind; your compliance advisers have the final word.
  • Employment Agencies Act 1973
  • Conduct of Employment Agencies and Businesses Regulations 2003
  • IR35 Off-Payroll Working Rules (Chapter 10 ITEPA 2003)
  • Agency Workers Regulations 2010
  • UK GDPR for candidate data processing
  • Right to Work checks under Immigration, Asylum and Nationality Act 2006
  • National Minimum Wage Act 1998
  • Pensions Act 2008 (Auto-Enrolment)
